Answer:
5.96
Explanation:
You want the measure of the side opposite the 34° angle in an obtuse triangle in which the side opposite the 28° angle is 5 units.
Law of sines
The law of sines tells you the ratio of side lengths is equal to the ratio of sines of their opposite angles.
x/5 = sin(34°)/sin(28°)
x = 5·sin(34°)/sin(28°) ≈ 5.96
The green box number is 5.96.
